Definitely not directly related but neither yahoo nor google or alexa or ... like being spidered. They have some very serious anti DOS/spider firewalling happening. To spider sites like these is a challenge, although it can of course be done. For a start don't admit to being a robot, pretend to be IE or if you want to pretend to be a robot make yourself googlebot or one of the well known spiders that people welcome.
I presume you are aware of robots.txt and what it does.
